GENERAL – Precautions Before Service00-15
PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B – Supplemental Restraint System (SRS).
For safe operations, please follow the directions and heed all warnings.
(2) Always use the designated special tools and test equipment.
(3) Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
has been disconnected. Serious injury may result from unintended air bag deployment if work
is done on the SRS system immediately after the battery cable is disconnected.
(4) Never attempt to disassemble or repair the SRS components. (SRS air bag control unit, air bag
module and clock spring.) If faulty, replace it.
(5) Warnings labels must be needed when servicing and handling SRS components. Warning labels
are located in the following locations.
Sun visor
Glove box
SRS air bag control unit
Steering wheel
Steering gear and linkage
Air bag module
Clock spring
(6) Store components removed from the SRS in a clean and dry place.
The air bag module should be stored on a flat surface and placed so that the pad surface is
facing upwards.
(7) Be sure to deploy the air bag before disposing of air bag module or disposing of a vehicle equipped
with an air bag. (Refer to GROUP 52B – Air Bag Module Disposal Procedures.)
(8) Whenever you finish servicing the SRS, check the SRS warning lamp operation to make sure
that the system functions properly.
2. Observe the following when carrying out operations on place where SRS components are installed,
including operations not directly related to the SRS air bag.
(1) When removing or installing parts do not allow any impact or shock to the SRS components.
(2) SRS components should not be subjected to heat over 93C, so remove the SRS components
before drying or baking the vehicle after painting.
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.

PROBLEM SYMPTOMS TABLE (FOR YOUR INFORMATION)
ItemsSymptom
StartingWon’t startThe starter is used to crank the engine, but there is no combustion within the
cylinders, and the engine won’t start.
Fires up and diesThere is combustion within the cylinders, but then the engine soon stalls.
Hard startingEngine starts after cranking a while.
Idling
stability
HuntingEngine speed doesn’t remain constant; changes at idle.
stability
Rough idleUsually, a judgement can be based upon the movement of the tachometer
pointer, and the vibration transmitted to the steering wheel, shift lever, body, etc.
This is called rough idle.
Incorrect idle speedThe engine doesn’t idle at the usual correct speed.
Engine stall
(Die out)The engine stalls when the foot is taken from the accelerator pedal, regardless
of whether the vehicles is moving or not.
Engine stall
(Pass out)The engine stalls when the accelerator pedal is depressed or while it is being
used.
DrivingHesitation, Sag“Hesitation” is the delay in response of the vehicle speed (engine speed) that
occurs when the accelerator is depressed in order to accelerate from the speed
at which the vehicle is now traveling, or a temporary drop in vehicle speed
(engine speed) during such acceleration. Serious hesitation is called “sag”.
(Refer to Figure 1.)
Poor accelerationPoor acceleration is inability to obtain an acceleration corresponding to the
degree of throttle opening, even though acceleration is smooth, or the inability
to reach maximum speed.
StumbleEngine speed increase is delayed when the accelerator pedal is initially
depressed for acceleration. (Refer to Figure 2.)
ShockThe feeling of a comparatively large impact or vibration when the engine is
accelerated or decelerated.
SurgeThis is repeated surging ahead during constant speed travel or during variable
speed travel.
KnockingA sharp sound like a hammer striking the cylinder walls during driving and which
adversely affects driving.
StoppingRun on
(“Dieseling”)The condition in which the engine continues to run after the ignition switch is
turned to OFF. Also called “Dieseling”.

MPI – Troubleshooting13-39
INSPECTION PROCEDURE 28
Power steering fluid pressure switch system
Probable cause
The presence or absence of power steering load is input to the engine-ECU.
The engine-ECU controls the idle speed control (ISC) servo based on this input.
Malfunction of power steering fluid pressure switch

Improper connector contact, open or short-circuited
harness wire

Malfunction of the engine-ECU
Check the power steering fluid pressure switch.NG

OK
Measure at the power steering fluid pressure switch connector
A-101.

Disconnect the connector, and measure at the harness side.

Check trouble symptom.
NG

INSPECTION PROCEDURE 29
A/C switch and A/C relay system
Probable cause
When an A/C ON signal is input to the engine-ECU, the engine-ECU carries out
control of the idle speed control (ISC) servo, and also operates the A/C compressor
magnetic clutch.
Malfunction of A/C control system

Malfunction of A/C switch

Improper connector contact, open or short-circuited
harness wire

Malfunction of the engine-ECU
Check the A/C compressor relay.
(Refer to GROUP 55 – On-vehicle Service.)NG
